I am on my second week of the Xulane patch. I am prescribed it to try and help my severe PMS. Within days of starting it, I have had serious heart burn. I didn't initially put the 2 together until I remembered that both times I was pregnant, I had debilitating heart burn. I've read that Xulane is high in estrogen in comparison to other birth controls. Has anyone else has this experience? If so. How long does it last? Does it eventually go away?
